My live video live chat starts at 3:00 p.m. Mountain Time (21:00 UT) today (Sunday April 27). If you look below and see/hear me nattering away about black holes or UFOs, then you’re in. I urge you to go to the UStream page, though, so you can participate in the chat room. If you want to change your nickname there, type "/nick JoeRogan" (or whatever) in the text field.

Great session Phil! I wish you’d change the chat, because for some reason it doesn’t work for me. I also wish you’d have an intermission or something, because I had to go to the bathroom but I didn’t want to miss anything
